Abstract (en)
The invention relates to improved convolutions of digital signals. When a first digital signal is convoluted with a second digital signal to obtain an output digital signal, to be converted afterwards using a limited number of bits. In order to prevent a loss of information, and therefore a degradation of the output digital signal upon the future conversion, at least one of the first and the second digital signal is formed of suitable values that store the information from the first digital signal within the most significant bits of the output digital signal.
